Post Air or Mixture Screw on PHBG 21 Dellorto (w Pic)??
So based on the "what side of the slide" logic, I believe the screw next to the idle screw is a FUEL mixture screw, and not air. However, there are several threads stating the screw next to the throttle screw is an air screw. Does anyone know with certainty? Would LOVE if someone could confirm!

I have just cleaned this carb from head to toe, and from what I see, both idle and fuel mixture screw start at 2 turns out. This is a stage6 70cc engine and legit/original Dellorto carb.

Thank you!!
